metacom: Analysis of the 'Elements of Metacommunity Structure'

Functions to analyze coherence, boundary clumping, and turnover
following the pattern-based metacommunity analysis of Leibold and Mikkelson
2002 <doi:10.1034/j.1600-0706.2002.970210.x>. The package also includes
functions to visualize ecological networks, and to calculate modularity
as a replacement to boundary clumping.
